Geronimo Stilton Reporter Vol. 7 : Going Down to Chinatown

When a 40 year old letter arrives at Geronimo's house
containing only a piece of a treasure map and a mysterious clue, Geronimo and
his friends set off to track down the recipient the envelope was intended for
all those years ago—even if that means going halfway around the world!
It's a globetrotting adventure for the generations!
